Safety Information |
The recommended use of isothiazolinone products by the manufacturers used as wrinkle releaser is not harmful. However, allergy to skin is one of the most reported issue with isothiazolinone. |
Applications |
Although isothiazolinones have no direct applications, their derivatives such as 5-chloro-2-methyl-4-isothiazolin-3-on and 2-methyl-4-isothiazolin-3 which are used together as preservatives in commercial households and cosmetics products, for instance, cleaners, shampoos, and washing materials. Notably, various products that use isothiazolinones are in the market, including shampoo, hand sanitizer, and lotions. Isothiazolinones is used in these products as an inhibitor of microbial activity that could lead to the product spoiling before the expected expiration date. |
